Bacterial cell-wall-associated fibronectin binding proteins A and B (FnBPA and FnBPB) form bonds with host fibronectin. This binding reaction is often the initial step in prosthetic device infections. Atomic force microscopy was used to evaluate binding interactions between a fibronectin-coated probe and laboratory-derived Staphylococcus aureus that are (i) defective in both FnBPA and FnBPB (fn...
Leptospira spp. are pathogenic spirochetes that cause the zoonotic disease leptospirosis. Leptospiral immunoglobulin (Ig)-like protein B (LigB) contributes to the binding of Leptospira to extracellular matrix proteins such as fibronectin, fibrinogen, laminin, elastin, tropoelastin and collagen. A high-affinity Fn-binding region of LigB has been localized to LigBCen2, which contains the partial ...
Assembly of fibronectin fibrils occurs at the surface of substrate-attached cells and is mediated by the first to the fifth type I modules in the N-terminal 70 kDa portion of the molecule. The first type III module (III1) of fibronectin, not present in the 70 kDa portion, contains a conformation-dependent binding site for the 70 kDa N-terminal region of fibronectin, suggesting that the III1 mod...
Polyethylene glycol (PEG) hydrogel microparticles generated via stop-flow lithography can be utilized for efficient microparticle-based cell culture processes because of their high biocompatibility, the molecular diffusion capability in gel structure, and tunability shape size. However, typical functionalization process PEG with cell-adhesion promoters has inevitable limitations, requiring addi...
Fibronectin and tenascin are large extracellular matrix proteins that interact with each other and with integrin receptors to regulate cell growth and movement. They are both modular proteins composed of independently folded domains (modules) that are arranged in linear fashion. Fibronectin is a covalent dimer and tenascin is a hexamer. The site on tenascin to which fibronectin binds has been l...
During tissue repair, fibronectin is converted from a soluble, inactive form into biologically active extracellular matrix (ECM) fibrils through a cell-dependent process. ECM fibronectin promotes numerous cell processes that are critical to tissue repair and regulates the assembly of other proteins into the matrix. Nonhealing wounds show reduced levels of ECM fibronectin. To functionally mimic ...
Vibrio vulnificus is a pathogenic bacterium that causes gastroenteritis and primary septicemia. To identify factors involved in microbial adherence to the host cells, we investigated bacterial proteins capable of binding to fibronectin, one of the main components comprised of the extracellular matrix of mammalian cells. A protein of approximately 35 kDa was purified from the extracts of V. vuln...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Of ten different cell lines examined, three showed distinct attachment and spreading on collagen IV substrates, and neither attachment nor spreading was enhanced by adding soluble laminin or fibronectin. This reaction was not inhibited by cycloheximide or antibodies to laminin, indicating a direct attachment to collagen IV without the need of mediator proteins. Cell-binding sites were localized...
A sequence of 1647 base pairs in length of Streptococcus mutans DNA that encodes for a 63-kDa protein with significant amino acid similarity with fibronectin-binding proteins of Streptococcus pyogenes and Streptococcus gordonii was cloned. The putative recombinant fibronectin-binding protein of S. mutans was purified using affinity chromatography and the cloned protein was used to prepare polyc...
